US Republican presidential candidate Donald Trump has ratcheted up his war of words against Democratic nominee Hillary Clinton as Election Day draws closer.

Speaking to his supports at a rally in Pensacola, Florida, on Wednesday night, the billionaire businessman said recent polls show that he is ahead in the race, and predicted a Republican victory on November 8.

"A lot of very, very big poll numbers coming down over the last few days," said Trump. "The new L.A. Times poll, highly respected, has us up 6 points nationwide.”

Trump is leading Clinton by 5.4 percentage points, according to the USC Dornsife/Los Angeles Times "Daybreak" poll, amid fading enthusiasm for Clinton since the renewal of the FBI’s investigation into her emails.  The poll tracks about 3,000 eligible voters until Election Day.

"In six days we are going to win the great state of Florida," Trump declared. "And we are going to win the White House."

“It's feeling like it already, isn't it?” he asked.

“We’ve got to be nice and cool, nice and cool. Alright, stay on point, Donald, stay on point. No sidetracks, Donald, nice and easy,” he said.

Trump also told his supporters that Clinton was unqualified to lead the country, and called her "totally unhinged." 

Meanwhile, Clinton lashed out at Trump for his comments against women and minority groups.

Speaking to supporters on Wednesday in the city of Las Vegas, Clinton said Trump is "out of his depth," and she called his foreign policy "incredibly dangerous."

"He doesn't have a clue," Clinton said.

She also painted a grim picture for minorities under Trump. She said her rival does not see Hispanics as Americans.

Clinton said Trump’s election would mean having a president who believes the lives of blacks are consumed by crime, poverty and despair.

The former secretary of state is losing support among voters after renewed controversy over her use of a private email server while she was head of the US State Department.

FBI Director James Comey told Congress in a letter made public on Friday that his agency was looking into new emails that may be connected to Clinton.

Clinton was investigated by the FBI over her use of the private server and how she handled classified information while she was secretary of state from 2009 to 2013. However, Comey concluded in July that there was not enough evidence to bring criminal charges against Clinton.

The FBI has revealed very little to the public about the new emails under investigation, except that they were uncovered during an unrelated investigation into former US congressman Anthony Weiner, the estranged husband of top Clinton aide Huma Abedin.

Clinton 'unhinged'

Trump was probably referring to an incident that happened on Tuesday night in Fort Lauderdale, Florida, when a protester accused Hillary's husband, former US President Bill Clinton, of being a "rapist".

“Bill Clinton is a rapist!” the demonstrator shouted at Hillary as she was speaking. Her demeanor changed instantly and she started screaming at the protester.

“You know, I am sick and tired of the negative, dark, divisive vision from people who support Donald Trump,” she shouted as the audience also started booing her.

“We are not going backwards, we are going forwards!” she yelled, but interestingly did not try to defend her husband, who was impeached in December 1998 over his lying about regarding an extramarital affair with former White House Intern Monica Lewinsky.

“So how do we do that? For the next seven days, we focus on what is important. Don’t get distracted. Don’t get diverted. Focus on the country and the world we want to help create,” she screamed.
